Dynamic Modeling and Simulation of Hybrid VTOL UAV

Abstract

Hybrid VTOL UAV is a simple combination of quad rotor and fixed wing UAV. It not only has the characteristics of the vertical take-off and landing of the quad rotor aircraft, but also has the cha-racteristics of long distance and high speed, so it has important application value. In the layout of the aircraft, the quad rotor is responsible for providing lift, working in the take-off and landing phase; after taking-off it will be converted to fixed wing flight mode. This paper establishes the dynamic equation of the aircraft, and build a Simulink simulation platform by using the method of PID closed loop control of the simulation. The results show that the design of the PID controller can make the output of the system has a good stability.
